SHIPPING momma-EL,

Application filed March 12, 1924., seen no. 698,764.

To all whom it may concern:

Be it known that I, CRANDALL U. Nonon'oss, a citizen of the UnitedStates, residing at WVinchendon, in the county of lVorcester and Stateof Massachusetts, have in vented a new and useful Shipping Receptacle,of which the following is a specification.

This invention relates to a shipping receptacle 1 suitable for shippingarticles of food that have to be chilled all the time, such as oysters,milk, and other foods. The principal objects of this-invention are toprovide a durable and strong receptacle that can be shipped longdistances for receiving ice or a freezing mixture effectively insulatedall around so as to reduce the entrance of heat; to provide it withmeans for holding a can for the food being shipped; and to provide animproved cover with means applied thereto to prevent leakage.

Reference is tobe had to the accompan ing drawings in which- Fig. 1 is acentral vertical sectional view of a shipping receptacle constructed inaccordance with this invention; and

Fig. 2 is a plan of the same partly broken away to show interiorconstruction.

I have shown the invention in a form in which it comprises a woodenshipping tub having a thick wooden wall for effectively insulating theice and also of course serving as a container for the whole device. Setinto a circular recess 19 in the bottom of this wooden wall is set theedge of a flat annular metal or wooden bottom plate 11 having a circularopening 12 through the center. In this opening is a circular closure 13substantially fitting it and provided with a rubber gasket 14: and lugs15 arranged circumferentially on the bottom of the closure and havingslanting bottom cam surfaces. Adjacent to these lugs are recessesthrough which permanent fixed lugs 17 on the bottom of the plate 11 areadapted to pass when the closure is put in place. The closure is thenswung around so that the cam surfaces 16 on the lugs will press downagainst the tops of these lugs 17 and hold the closure firmly in place.A handle .18 for operating it extends diametrically across the bottom.

At or near the top of the tub 10 its inside surface is provided with acircular recess 20 extending all the way around it and in this islocated the edge of a flat metal or wooden top plate 21. This plate likethe plate 11 is set into place in therece'ss the tub during themanufacture of the latter. The plate 21 is provided with a sheet metalconical Wall 22 extending down from its edge and slanting inwardly toprovide a dead air space inside to prevent the passage of heat. Theplate 21 is alsopr'ovided' with lugs 17 like those on the bottom of thedevice for the same purpose.

The plate 21 is" centrally perforated and supports within thisperforationa stationary ice-cream can 2 1. This can is bent outwardly atits top to form a conical surface 25 and has a circular rib 33 under theperforation to fix it in stationary position in the plate 21. Theconical plate 22 can be permanently secured to it for that reason. Abovethe conical surface 25 there is a circular recess 26 in the plate 21 inwhich fits a circular flange 27 on the edge of the top closure 28. Thistop closure consists of a circular plate of metal having a pair ofnotches 29 located opposite each other for the passage of the lugs 17 onthe plate 21. Adjacent to these notches are inclined surfaces 16constituting cams for engaging under the lugs 17 and holding the closuredown.

This closure is provided with a horizontal circular recess 30 in whichfits a fiat annular rubber packing ring let described in connection withthe bottom closure. This rubber packing ring is not secured to the metalclosure 28 but is stretched out and allowed to spring into the recess 30which holds it in position so that its top and bottom surfaces arehorizontal. It projects out to the end of the recess 26 and rests on theupper surface which constitutes the bottom of that recess. The closurealso has a radially projecting handle 31 by which it can be manipulatedto turn it as much as necessary to secure it and unlock it.

This provides a very substantial shipping receptacle, one in which thefood can does not have to be turned or removed and, in fact, cannot be,and the ice is insulated from the entrance of heat by the wooden bucketand by the air space above the wall 22. The covers 13 and 28 both at thebottom and top are packed and leakage prevented by the rubber gaskets14. The opening of the two covers is a very simple matter and they arevery effectively closed against accidental opening.

This shipping tub is of very stable con 7 ill struction, being made allof wood and the can 24 is permanently fixed in position and does'notneed to be taken out except for cleaning, repairs or replacement. Itwill retain the food in chilled condition a long time on account of theinsulation all around.

Although I have illustrated and described only one form of theinvention, I am aware of the fact that modifications'can be made thereinby any person skilled in the art without departing from the scope or"the invention as expressed in the claims. Therefore I do not wish to belimited to all the details of construction herein shown and describedbut what I do claim is :r

1. As anfarticleoi manufacture, a ship ping receptacle comprising awooden tub having an annular top with an opening in the center, said tophaving a dead'air space surrounding the opening for insulation, a

food can fixedly mounted in said opening and projecting therefrom downinto the tub, a removable closure over the can supported by the annulartop and having cam surfaces for holding it locked in position, and abail for carrying the tub.

2. The combination with a shipping receptacle, of a closure thereofcomprising a circular metal plate having an annular horizontal recessaround it, the closure projecting beyond thev inner edge of the recessat the center, and a flat annular rubber ring fitting in said recessandheld in position thereby, the closure having a flat surface above thering against which the ring is adapted to be pressed when the closure isclamped in position. I

In testimony whereof, I have hereunto affixed my signature.

CRANDALL U. NORCROSS.
